The gem is one of the largest diamonds discovered in Russia.
Alrosa (MCX:ALRS), the world’s top diamond producer by output in carats, has unveiled the recovery of a 241.21 carat rough diamond from its Nyurbinsky open-pit mine in Russia.
The gem measures 38.64 millimeters by 27.34 millimeters by 25.46 millimeters and is translucent with a grey hue. Its intermediate and peripheral zones have cracks and contains graphite and sulphide inclusions, according to Alrosa.
The company said it is one of the largest rough diamonds recovered in the Russian Federation, and third largest found at the Nyurba Mining and Process Division.
Nyurba Mining and Process Division is one of Alrosa’s youngest divisions, which operates the Nakyn ore field and develops Nyurbinksy and Botuobinsky open-pit mines.
Aura’s Nuyrbinsky open-pit mine has been in operation since 2001. In January 2015, identified reserves totaled 36.9 million carats.
Year-to-date, shares of Alrosa have increased 26.47 percent—a $14.81 jump—to $70.75.
This isn’t the only large diamond to be found as of late. Lucara Diamond (TSX:LUC) made the largest discovery of 2015 at its Karowe mine in Botswana. The diamond is the second-largest gem-quality diamond ever recovered, and could sell for $70 million at the Sotheby’s auction on June 29.
